Hi. i'm 19 and i have irregular menstrual cycles.. which is why i never bothered mapping them.. but just last aug. 19, me and my bf had sex.. well, not that he came inside me.. he didn't for the whole time but i understand there's sperm even in precum... so now, i'm worried that i'm pregnant.. although it might just be me being paranoid... so from one month back like july i had my last period.. and now i still don't... ordinarily, i would just treat this as normal.. but then my bf started asking me why i still didn't have my period and i'd tell him over again that its just normal for me coz i'm an irregular.. but then.. i noticed my nipnips have gotten very sensitive and a slight touch can make me ouch.. and they've gotten darker too.. please enlighten me... :)
PMS is my guess
